Although we want to genuinely reward consecutive logins, and free daily spins, they should not be too easily exploited, or else the rewards won't feel like rewards anymore. Therefore, certain limitations were placed:

The Jackpot Wheel requires you to have emeralds on the account. If you login on consecutive days, and the Daily Prizes award emeralds after a certain number of logins. Thereby giving you access to the Wheel afterwards.

The Daily Prizes are available up to level 30 to help developing characters. Since the emeralds are shared among characters of the same account, login consecutively on lower-level characters to get those first emeralds, and you will be able to use the Wheel for your higher-level character on that account.
